Free tools for Meta advertisers.

Small, focused tools for the everyday work of running Facebook & Instagram ads — no signup, no catch. Built by the team behind Harry, the AI media buyer for agencies.

Ad mockup generator

Preview your ad exactly as it appears in the Facebook and Instagram feeds before you launch. Upload a creative, add your copy, and see it live.

ROAS calculator

Find the exact return on ad spend you need to break even — and the target ROAS to hit your profit goal. Includes break-even CPA.

UTM builder

Generate clean, consistent UTM tracking URLs — with one-click Meta dynamic parameters like {{campaign.name}} and {{ad.name}}.

Ad naming generator

Build a consistent ad naming convention from dynamic tokens — client, campaign, objective, format, date — so every ad name matches.

Like the tools? You'll love the platform.

Harry builds, previews, and launches whole Meta campaigns — from ChatGPT, Claude, Cursor, or in-app.
